WATCH-CASE.

JPECIPCATION forming part of Letters Patent No. 322,680I dated July 2l,1885.

Application filed A pril 1T, 1885.

To @ZZ whom it may concern:

Bc it known that I, WILLIAM CARPENTER, of Salida, county of Chaffee,Colorado, have invented a new and useful Improvement in Vatches, ofwhich the following is a full,clear, and exact description.

This invention relates to certain new. and useful improvements inwatch-cases having dust-prooi'joints, and the object of my invention isto facilitate placing and adjusting the works in the case.

The invention consists in the combination` with awatch-case,ofamovement-holding band or ring and a link hinged to the case and to thesaid band or ring.

rlhe invention also consists in parts and details and combinations ofthe same, as herein shown and described.

Figure l is a face view of a watch provided with my improved case,theworks being partly raised. Figs. 2 and 3 show sections of the watch withthe works in different positions. Fig. i is a longitudinal sectionalView of the watch closed.

The watch-case A has a screw-neck, B, on its face,on which neck thebezel C is screwed. The ring, casing, or band D for receiving themovement or works is hinged at its bottom edge to one end ot' a link, E,having the other end hinged to the case A at the base of the pendant F.The link E has a longitudinal slot, G, through which the winding-pin Hof the works can pass. The pendant F has a neck, J, on its outer end,onwhich neck a leftliand screw-thread is cut, and on which neck a crown,K, can be screwed, from the inner end of which a tube, L, projectsthrough the pendant, the said tube having a plate, M, on its inner endprovided with a squared aperture, N, for receiving the squaredwindingpin H. In the tube L a plunger 0r piston, O, is arranged, whichis pressed toward the inner end of the tube by a spiral spring, P,interposed between the plunger and the outer end of the said tube. Aroun'd stem or plug, Q, fitting in the aperture N of the plate Mprojects from the said plunger. The works are held as shown in Fig. 2,or are swung over toward the pendant, as may be desired, and as theadjustment, dre., of the works may require.

To place and hold the worksin the case,the

(No model.)

works are raised and the link E swung down to permit the windingpin H topass through the slot G- and into the squared apertures in the endplate,M, so that the said winding-pin can be turned by the crown K andtube L. The entering winding-pin H pushes back the plunger or piston Cand compresses the spring P. When the works are swung up, the stem orplug Q follows the receding loose pin H and presses it into the works,thus preventing the pin H binding or being held in the apertured plate Mand withdrawn from the movement. By hinging the works in the manner setforth a much longer pin, H, can be provided than in works hinged incases in the usual manner, and as the pin H is longer the plate M gets abetter grip on it.

As set l'orth above, the loose winding-pin always remains in the works,and is not withdrawn by the apertured plate M, which is of great value,as much trouble is caused by the pins H being held by the windingattachment in the pendant. The spring I presses the winding-crown K fromthe end of the pendant, and thus permits of turning the crown to theright or left for setting the hands without screwing said crown on thependant. After winding the watch the crown K is turned to the left, andis thereby screwed on the pendant and forms an absolutely tight joint.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. The combination, with a watch-case,of amovement-holding band or ring connected with the case by a link hingedto the case and to the movement-holding ring or band, substantially asherein shown and described.

2.V The combination, with a watchcase, of a movement-holding band orring and a link hinged to the case and to the said ring or band at thebottom edge of the same, substantially as herein shown and described.

The combination, with a watch-case, of a movement-holding band or ringand a slotted link hinged to the said band or ring and to the case atthe pendant, substantially as herein shown and described.
